Carbiide sibidhka ah waa walxo daawaha ah oo ka samaysan iskudhisyo adag oo biraha refractory iyo biraha isku xidhka ee habka biraha budada ah.Caadi ahaan waxaa laga sameeyaa walxo iskuxiran oo jilicsan (sida cobalt, nikkel, birta ama isku dhafka walxaha kor ku xusan) oo lagu daray walxo adag (sida tungsten carbide, molybdenum carbide, carbide tantalum, karbide chromium, carbid vanadium, carbide titanium ama iyaga isku dar ah).
Carbid sibidhka ah ayaa leh taxane ah sifooyin aad u fiican, sida qallafsanaanta sare, xidhashada caabbinta, xoogga wanaagsan iyo adkaanta, caabbinta kulaylka, iska caabinta daxalka, iwm, gaar ahaan qallafsanaantiisa sare iyo adkaysiga xidhashada, kuwaas oo asal ahaan aan isbeddelin xitaa at 500 ℃ oo weli leh adkaanta sare ee 1000 ℃.Qalabkayaga caadiga ah, adayggu waa mid sare ilaa hoose: dheeman sintered, boron nitride cubic, cermet, carbide sibidhka, birta xawaaraha sare leh, iyo adkaanta waa hoose ilaa sare.
Carbide sibidhka ah ayaa si weyn loo isticmaalaa sida qalabka wax lagu gooyo, sida qalabka rogid, mishiinnada wax lagu shiidayo, qorayaasha, qashinka laydhka, gooyayaasha caajiska ah, iwm., birta caadiga ah, iyo sidoo kale jarista birta kulaylka u adkeysata, birta birta ah, birta manganese sare, birta qalabka iyo kuwa kale oo ay adagtahay in lagu sameeyo qalabka mashiinka.
Carbiid sibidhku waxa uu leeyahay adayg sare, xoog, xidhashada caabbinta iyo iska caabinta daxalka, waxaana loo yaqaan "ilkaha warshadaha".Waxaa loo isticmaalaa in lagu soo saaro qalabka wax lagu gooyo, qalabka goynta, qalabka cobalt iyo qaybo u adkaysta.Waxaa si weyn loogu isticmaalaa warshadaha militariga, hawada hawada, machining, metallurgy, qodista saliidda, qalabka macdanta, isgaarsiinta elektarooniga ah, dhismaha iyo beeraha kale.Iyadoo horumarinta warshadaha hoose, baahida suuqa ee carbide sibidhka ah ayaa sii kordheysa.Iyo mustaqbalka, soo saarista hubka tignoolajiyada sare iyo qalabka, horumarka sayniska iyo tignoolajiyada casriga ah iyo horumarinta degdega ah ee tamarta nukliyeerka waxay si weyn u kordhin doontaa baahida alaabada carbide sibidhka leh oo leh teknoolojiyad sare iyo xasillooni tayo sare leh. .
Sannadkii 1923-kii, Schlerter ee Jarmalku wuxuu ku daray 10% - 20% cobalt budada tungsten carbide sida binder, wuxuuna ikhtiraacay daawaynta cusub ee tungsten carbide iyo cobalt.Adaggeedu waxa uu ka hooseeyaa dheemanka, kaas oo ah karbidhida sibidhka ee ugu horreeya adduunka.Marka la gooyo birta oo leh qalab ka sameysan daawadaan, daabku si dhakhso ah ayuu u xiran doonaa, xitaa daabku wuu dillaaci doonaa.Sannadkii 1929-kii, Schwarzkov ee Maraykanka ayaa ku daray xaddi gaar ah oo ka mid ah karbides-ka isku dhafan ee tungsten carbide iyo carbide titanium si ay u abuuraan asalka, taas oo wanaajisay waxqabadka qalabka birta.Tani waa guul kale oo laga gaaray taariikhda horumarinta carbide sibidhka.
Carbide sibidhka ah waxa kale oo loo isticmaali karaa in lagu sameeyo qalabka qodista dhagaxa, qalabka macdanta, qalabka wax lagu qodo, qalabka wax lagu cabbiro, qaybaha xidhashada adkaysi u leh, abrasives biraha, xadhkaha dhululubo, biraha saxda ah, nozzles, caaryada hardware (sida caaryada sawirida silig, caaryada boodhka, lowska caaryada, iyo caaryada xiraha kala duwan.
Labaatankii sano ee la soo dhaafay, kaarbiid sibidh ah oo dahaarka leh ayaa sidoo kale soo muuqday.Sannadkii 1969kii, Iswiidhan waxay si guul leh u samaysay qalab dahaarka leh oo kaarbiide titanium ah.Substrate-ka qalabku waa tungsten titanium cobalt sibidhka carbide ama tungsten cobalt carbide sibidhka.Dhumucda lakabka carbide titanium ee dusha sare waa dhowr microns, laakiin marka la barbar dhigo qalabka daawaha ee calaamad isku mid ah, nolosha adeegga ayaa la kordhiyaa 3 jeer, xawaaraha goynta ayaa kordhay 25% - 50%.Jiilka afraad ee qalabka dahaadhka ayaa soo muuqday 1970-yadii, kuwaas oo loo isticmaali karo in lagu gooyo alaabta ay adag tahay in la mariyo.
